Definitions

  • the present invention relates to a sensor-detachable illumination device to which a sensor is attached in a detachable manner.
  • FIG. 25 schematically illustrates a conventional illumination device 40 as obliquely seen from below.
  • the illumination device 40 is fixed to a ceiling or the like and includes an illumination lamp 41 such as a fluorescent tube, a sensor 42 for use in controlling the lighting operation of the illumination lamp 41 and a sensor attachment unit 44 through which the sensor 42 is attached to a device housing 43.
  • the sensor 42 includes, e.g., a sensing unit 42a for detecting the presence of a person and a sensing unit 42b for detecting the brightness.
  • the sensor 42 is attached to the sensor attachment unit 44 so that the sensing units 42a and 42b can be exposed to the outside.
  • Figs. 26A and 26B show the external appearance of the sensor attachment unit 44 employed in the illumination device 40.
  • Fig. 26A illustrates a state that the sensor 42 is not attached to the sensor attachment unit 44
  • Fig. 26B illustrates a state that the sensor 42 is attached to the sensor attachment unit 44.
  • the illumination device 40 undergoes a remarkable change in outward appearance in the vicinity of the sensor attachment unit 44 depending on the attachment and detachment of the sensor 42. If the sensor 42 remains attached at all times, the illumination device 40 will undergoes no change in outward appearance and therefore will pose no problem in design.
  • the illumination device 40 is of the type capable of exercising a specified function without resort to the sensor 42, a problem in design is posed in that the outward appearance of the illumination device 40 varies depending on the presence or absence of the sensor 42. In other words, the sensor attachment unit 44 of the illumination device 40 is exposed in case where the sensor 42 is not attached in place. This leaves a conspicuous difference in outward appearance between the illumination device 40 without the sensor and another illumination device with a sensor. In case where an illuminating system includes a plurality of illumination devices 40, the system lacks uniformity in outward appearance and suffers from a big problem in design if the respective illumination devices 40 differ in outward appearance from one another.
  • the senor 42 and the sensor attachment unit 44 are electrically connected to each other by a connector 44c or the like.
  • the connector 44c remains exposed when the sensor 42 is not attached to the sensor attachment unit 44. In this state, the charging terminal of the connector 44c is exposed to the outside, meaning that a user may inadvertently touch the charging terminal of the connector 44c. This is undesirable from the standpoint of product quality and safety.
  • Another object of the present invention is to provide a sensor-detachable illumination device that can keep small the change in outward appearance between a state in which a sensor block is detached from a sensor attachment unit and a state in which the sensor block is attached to the sensor attachment unit, thereby improving the design merit and assuring the reliability in remote control communication.

  • an illumination device including: a device housing; an illumination lamp installed to the device housing; a sensor for use in controlling the lighting operation of the illumination lamp; a sensor attachment unit through which the sensor is detachably attached to the device housing, the sensor attachment unit having a connector; and a decoration member attached to the sensor attachment unit, the decoration member serving to cover the sensor with a sensing unit of the sensor exposed to the outside when the sensor is attached to the sensor attachment unit, and to hide the connector of the sensor attachment unit when the sensor is not attached to the sensor attachment unit.
  • an illumination device including: a device housing; a remote control signal receiving unit for receiving a remote control signal transmitted from a remote control terminal; a sensor block detachably attached to the device housing and exposed from the device housing; and a sensor attachment unit provided in the device housing for holding the sensor block in place, the sensor attachment unit having a connector, wherein the sensor attachment unit has a surface substantially flush with a surface of the remote control signal receiving unit when the sensor block is not attached to the sensor attachment unit, wherein the sensor block overlaps with the surface of the remote control signal receiving unit when the sensor block is attached to the sensor attachment unit, and wherein the sensor block includes a conduction portion for delivering the remote control signal, the conduction portion being formed in the portion of the sensor block overlapping with the surface of the remote control signal receiving unit.

  • the decoration member 15 is attached to the sensor attachment unit 14 when the sensor 12 is not attached to the latter. In other words, the sensor 12 and the decoration member 15 are interchangeably attached to the sensor attachment unit 14.
  • the illumination lamp 11 As the illumination lamp 11, a fluorescent tube, an incandescent light bulb, a light emitting diode (LED) lamp or the like can be used.

  • the control of the illumination lamp 11 includes on-off control, phase control, pulse width control, amplitude control and the like.
  • the sensor 12 includes, for example, a human sensor and/or a brightness sensor.
  • the human sensor includes, e.g., a pyroelectric element for sensing infrared rays, and detects the presence of a person within a specified range by sensing infrared rays emitted from a body of the person.

  • the connectors 12c and 14c include a power supply terminal for supplying an electric current from the device housing 13 to the sensor 12 through the sensor attachment unit 14 and a signal terminal for transmitting an output signal from the sensor 12 to the lighting control circuit in the device housing 13 through the sensor attachment unit 14.
  • the connectors 12c and 14c are electrically connected to each other when the sensor 12 is attached to the sensor attachment unit 14.
  • the power supply terminal of the connector 14c serves as a charging terminal, so that it is preferable to use the connector 14c as a female connector and the connector 12c as a male connector so as to prevent the charging terminal from protruding from the sensor attachment unit 14.
  • the connectors 12c and 14c can also serve as a holding structure for keeping the sensor 12 attached to the sensor attachment unit 14.

  • the lighting operation of the illumination lamp 11 is controlled by the output signal of the sensor 12 while the sensor 12 remains attached to the sensor attachment unit 14.
  • the illumination device 10 lights up the illumination lamp 11 and keeps the illuminance constant by controlling the dimming rate of the illumination lamp 11 so that the brightness measured by the brightness sensing unit 12b of the sensor 12 becomes constant. If the human sensing unit of the sensor 12 fails to detect a person for a predetermined time, the illumination device 10 extinguishes the illumination lamp 11 to save energy.
  • the decoration member 15 is attached to the sensor attachment unit 14 instead of the sensor 12 , the illumination lamp 11 is turned on or off by the on-off operation of the electric power supplied to the illumination device 10 or by the control signal fed from other illumination devices.

  • Fig. 17 is a side view showing the sensor block 204.
  • the remote control signal moves through the conduction portion 206 and arrives at the remote control signal receiving unit 203.
